ELMER E. ALLBEE, OF ARLINGTON, NEW J ERSEY, ASSIGNOR TO SAFETY CAR HEATING & LIGHTING COMPANY, A CORPORATION OF NEW JERSEY.

VALVE FOR TRAIN-PIPES.

To all whom it may concern:

Be it known that I, ELMER E. ALLBEE, a citizen of the United States, residing at Arlington, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Valves for Train-Pipes, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to valves for controlling the fiow of fluids under pressure, and more particularly to valves adapted for use in railway cars or similar structures.

One of the objects of the invention is to provide a valve of the above character of simple, durable and compact construction.

Another object is to provide a valve particularly adapted for use in the above relation which can be easily operated from the outside of the car either above or below the platform thereof, and which may be opened or closed with a minimum amount of movement.

Other objects will be in part obvious and in' part pointed out hereinafter.

The invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplifiedn'n the construction hereinafter set forth, and the scope of the application of which will be indicated in the following claims.

,In the accompanying drawings, wherein is shown one of various possible embodiments of my invention, Figure 1 is a front elevation of my improved valve. Fig. 2 is a horizontal sectional view taken substantially on line 2-2 of Fig. 1. Fig. 3 is an elevational View of the interior of the casing showing the valve open, one of the sections of the valve casing removed. Fig. 4 is a similar view but showing the valve in a closed position. Fig. 5 is a view showing the valve mounted upon the end of a train pipe of a railway car together with the mechanism employed for operating the same.

Similar reference characters refer to similar arts throughout the several figures of the drawings.

Referring now to the drawings, 1 indicates the platform of a railway car beneath which extends a train pipe of usual construction, a part of which is shown at 2.

The valve shown at 3 is mounted upon Specification of Letters Patent.

Application filed April 16, 1908.

Patented July 12, 1910. Serial No. 427,319.

-in turn is secured to the sills of the railway car. Valve 3, in the present instance, is constituted by a pair of chambered sections, as at 7 and 8, which are suitably joined as by means of screw threads 10. Section 7 is provided with an admission port 11, with which the train pipe communicates, and section 8 is provided with a discharge port 12 from which leads a conduit 13, to the end of which is attached acoupler section 14, as shown in Fig. 5 of the drawings. The direction of flow of the fluid through the valve is indicated by the full barbed arrows. The inner side of section 8 of the valve casing which, in the present instance, is the pressure side thereof and adjacent the discharge port 12, is machined oif smooth to provide a valve seat, which is adapted to receive an oscillatory valve member 15. This valve, in the present instance, is formed by a metallic member of less diameter than the interior wall of the casing, and has its opposite edges on arcs, described by a radius equal to that describing the circumference of the inner wall of the casing, so that when said valve member is oscillated in either direction the edges thereof will abut the inner wall of the casing which will operate as an abutting stop therefor. The shape of this valve member, which is substantially that of a gibbous, is clearly shown in Figs. 3 and 4 of the drawings. The half barbed arrows indicate the direction of movement of the valve when thesame is oscillated to open or close the discharge port. The discharge port 12 lies between the edge of valve member 15 and the inner wall of the casing when the valve is swung to the position shown in Fig. 3 of the drawings. Valve 15 is pressed tightly against its seat by means of spring means which engages the side of the valve member opposite to that which engages the valve seat. This spring means, in the present instance, comprises a cap 16 adapted to telescope wit-hm a socket 17, formed upon the valve member 15, said-cap engaging with an apertured partition 18 which extends across section 7, a spring 20 being located within said cap and urgingthe latter and said valve member to movement in opposite directions.

'Valve member 15, near one of its edges,

is provided with a rectangular or square instance, is connected a lever 25, which in turn is connected by a link 26 to a collar 27 mounted upon a vertically reciprocating rod' 28, one end of which extends upward through the platform of the car, the opposite .end thereof being guided in a bracket 30. A handle 31 is formed upon this rod below the platform of the car, and the handle 32 is formed upon the upper end of the rod above the platform.

The operation of my invention, which should be obvious from the above description, may be briefly described as follows The parts are so adjusted that when the handles 81 and 32 and lever 25 are in the position shown by full lines in Fig. 5 of the drawings, the valve member 15 is in the position shown in Fig. 3 of the drawings with the discharge port 12 open. To close the valve, the handle 31 may be lifted to the position shown in dotted lines in Fig. 5, the parts-being held in such position by means of a pin 33, provided in the rod 28, which engages with a plate 34: provided upon the platform. The mechanism may be similarly operated from above the platform by lifting handle 32. The lifting of rod 28 operates ing. It will accordingly be seen that I have provided mechanism Well adapted to attain, among others, all the objects and ends above enumerated in a simple and efiicient manner...

The valve structure is composed of few parts and occupies a minimum space beneath the platform of the car. A further advantage inherent in the present invention resides in the fact that the valve may be opened or closed with a minimum amount of oscillatory movement. i

As many changes could be made in the above construction and many apparently wldely different embodiments of this invent1on could be made without departin from the scope thereof, it is intended that a lmatter contained in the above description or shown 1n the accompanying drawings shall be nterpreted as illustrative and not in a limiting sense. It is also to be understood that the langua e used in the following claims isintende to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
